' 'z claims. (c1. asv-23s) This invention relates to heat exchangers and more particularly to coolers for cooling various liquids, particularly about petroleum refineries, Such as the jacket water of internal combustion I engines, petroleum oils or parts thereof, when pumped through a pipe.

An object of the presentinvention is to provide -a cooler as specified which may be quickly, easily and thoroughly cleaned without discon- 10 necting any of the line connections thereof, either those through which the liquid passing through the' tubes of the cooler is pumped or those of the,

water or other liquid circulating through the jacket of the cooler. i

Morespecically, the present invention embodies a cooler comprising an outer shell composed of a plurality of sections, certain of which are telescopically associated, while other sections are removable, to permit access to the tubes *l u of the cooler for cleaning sediment from the interior of the casing and from about the tubes.

With these and other objects in view, as may appear from the accompanying specification, the i invention consists of various features of construc- 25 tion and combination of parts, which will be first described in connection with the accompanying drawings, showing a cooler of the preferred form embodying the invention, and the features formling the invention will be specifically pointed out n in the claims.

In the drawings:

Figure 1 is a side elevation of the improved cooler having parts thereof broken away.

Figure 2 is a cross section through the improved cooler taken on the line 2-2 of Figure 1.

Figure 3 is a cross section through the improved cooler taken on the line 3-3 of Figure 1.

Figures 4 and 5 are detail elevations of support plates employed in the cooler structure.

40 Figure 6 is an enlarged fragmentary section taken on the line 6 6 of Figure 1.

Figure 7 is a detail section taken on the line 1--1 of Figure 1.

Figure 8 is a detail end view of a part of the casing of the cooler.

Figures 9, 10, 11, 12 and 13 are detail views in side elevation showing different positions of the parts of the cooler, so as to permit cleaning so thereof, and specifically Figure 9 shows the cooler withV the casing removed.

Figure 10 shows the cooler in side elevation with all of the casing sections in place.

Figure 11 is a side elevation of the cooler showu lng one section of the casing telescoped over the other section so as to permit the removal of the sectional portion of the casing. v

Figure 1,2 is a viewsimilar to Figure 11 showing .the removable sections removed.

Figure 13 is va view showing how the smaller section may be telescoped into the largersection to permit access to the tubes for cleaning.

Referring more particularly to the` drawings, the improved cooler comprises .the casing I which is composed of the smaller tubular section 2, the larger tubular section 3, the inner ysection 4 and the inlet and outlet heads and 6 respectively for the liquid which circulates through the casing. 'Ihe tubes 1 have their ends attached in the usual manner to tube heads 8 and 9. The tube heads 8 and 9 arewelded, as shownat I Il, to the ends of the tube or casing forming the inletvand outlet` heads 5 and 6. Inlet and outlet heads II and I2 for the liquid pumped through the tubes 'l are detachablyconnected to the tube heads 9 in any suitable manner such as by means of the anges I3 and bolts I4, The heads II and I2 have flanges I5 thereonby means of which they may be connected to the pipes of the pipe line in which the cooler is interposed.

'Ihe inlet head 5 has an inlet connection I6 connected thereto and opening into the inlet head preferably from the bottom while Athe outlet head 6 has an outlet pipe I1 connected thereto, preferably at the topmost portion thereof so as to carry away any air, gas or vapor from the interior of the casing I.

The section 2 of the casing has a flange I8 formed on its outer end by means of which it is attached to the flange I9 of the head 6 and it is smaller in diameter than the section 3 of the casing, 'Ihe inner end of the smaller section 2 extends into the inner end of the larger section 3 as clearly shown in Figure 6 of the drawings.

Packing shown at 20 is mounted about the inner end of the smaller section 2 and within the larger section 3 and is held in place and compressed by a packing gland 2i which is in turn connected to a flange 22. The flange 22 may be welded or otherwise suitably attached to or formed upon the inner end of the larger section 3.

'I'he inner section 4 is placed within the larger section 3 of the casing and it is formed of a plurality of sections 23 and 2l as clearly shown in the drawings. The sections 23 and 24 engage in longitudinal edgewise engagement as clearlyr shown in Figure 3 of the drawings so as to form a continuation of the casing through which the liquid circulates, and their inner diameter is substantially equal to the inner diameter of the section 2. The inner ends of the sections 23 and 2l engage against the inner end of the section 2 while their outer ends engage against the inner end of the head 5. In the drawingsthe inner casing 4 is shown as made of only two sections with their joints in a horizontal plane, but it is to be understood that this inner casing section may be made in any number of pieces or sections without departing from the spirit oi' the present invention, and that their engaging joints may be disposed in any desired practical plane and particularly in a vertical plane, so as to permit them to fall outwardly when the larger section 3 is telescoped over the smaller section 2.

The larger section 3 has a iiange 26 on its outer end which is detachably connected in any suitable manner such as by bolts 28 to the flange 21 on the head 5.

With coolers of approved type heretofore in use. it has been necessary to disconnect the pipe connections to the cooler and use considerable force for cleaning the cooler of sediment, entailing considerable expense and also requiring that the cooler be taken of! of the line and completely disconnected during the cleaning operation. With the present invention, the interior of the casing and the exterior of the tubes may be thoroughly cleaned, easily and in a Vshort space of time, without requiring the rdismembering or disconnecting of any of the pipe connections with the cooler.

When it is desired to clean the cooler, the large section 3 is telescoped over the small section 2, as shown in Figure 11 of the drawings, the only disconnecting operation necessary being that of disconnecting the flanges 26 and 21. After the large section 3 has been telescoped overl the small section 2, the inner casing l will be exposed so that the sections 23 and24 thereof may be removed as shown in Figure 12 of the drawings, exposing the tubes 1 of substantially one-half of the length of the cooler, so that the sediment may be easily cleaned from the exposed portions of the tubes. After the portion of the tubes 1 which is normally housed within the inner casing section I have been cleaned the casing sections 3 and 2 are then moved over the cleaned portions of the tubes exposing the tubes of the other half of the cooler and permitting them to be thoroughly cleaned. After they have been cleaned, the casing sections 2 and 3 are again moved to the normal position of the smaller section 2 and the removable section I is placed in position, after which the larger section 3 is moved or slipped over and the entire cleaned' cooler is again ready for operation.

The tubes 1 may be supported at spaced points along their lengths by support sheets 30, each of which forms only a segment of the interiorv of the casing. The support sheets 30 are arranged staggeredly, as shown in Figure 9 of the drawings, so as to cause the cooling fluid to pass through the cooler in a sinuous path.

It will be understood that the invention is not to be limited to the specific construction or arrangement of parts shown but that they may be widely modified within the invention deiined by the claims.
